#1 Is this a refrigerated air conditioner and can hose go out sliding door my son need one for a high rise unit and also is it noisy
Yes this is a Portable cooling only air conditioner these are required to be exhausted to the outside using the exhaust kit provided as per our website information the exhaust kit is suitable for Vertical and Horizontal windows only these were never designed for sliding doors. All air conditions will have to make some sort of noise as the unit will be inside the property these are generally as noisy as a working dishwasher.
#2 How long is the exhaust hose? What size vertical windows will the exhaust hose fit into?
The length of the hose is 1.2 meters exactly. The thickness of the hose is 130mm and the unit is provided with a single hole bracket that allows you fill the opening of the window to avoid losing cool air.
#3 What is the maximum size area (room) this will operate efficiently in?
Thank you for this question as per our website listed under the Note section we have added this extra information: Notes Window Kit is suitable for Horizontal & Vertical windows only. Now you could still use this air conditioner but you will need to be able to create a panel to insert the duct kit into these were never designed for that style of window, maybe a thick foam insert would work well
